Microbiology is the name given to the branch of science that does not observe the small microorganisms that can not be seen. Microorganisms can be found on all surfaces, in air, in water and in food. These organisms proliferate rapidly after infestation and cause enzymatic changes and cause the degradation of foods by synthesizing new compounds or by breaking down existing compounds.

Gıdalara-infected pathogens pose a risk for human health. Therefore, microbiological analysis of foods and feedstuffs based on sterile conditions and scientific methods is very important in terms of obtaining healthy and standardized results and therefore protecting consumer health.
